Just pulled a Hinemoa out of the water up a steep ramp. We had a steel cradle with supports for the hull sides that was long enough to have 2 wheel barrow/dinghy trolley inflatable wheels at each corner. The wheels had sufficient buoyancy to keep the cradle afloat whilst it was moved out and under the boat.
We then attached ropes from the back of each cradle to the associated stern (to transfer the pull from cradle to boat) and lashed the cradles firmly in place using lines going up and over the beams.
A long bridle was attached to the two cradles which was in turn attached to a 4 to one purchase. The purchase was attached to a car tow hook. The boat was extracted by a combination of taking up the purchase and moving the car.
No problems.

hi - thanks for photos - you are giving me some great ideas for launch but how do you assemble the boat? or from your photos, if you now wanted to drive somewhere what would you do?!
Thanks Johnny
PS saw your blog about charted in bahamas - looks amazing. I spent two weeks on wild tamarind near staniel!

This ramp is about 7-8 miles from our shop. We use a pilot vehicle in front a back with strobes and wide load signs and pick a low traffic time. We assemble the boat in cradles in our yard a lift it with a crane and back the trailer under it. When we move a boat further we have another larger trailer and go to a yard with a crane and a travel lift for launching. We are going to build a trailer to self launch the Tiki 8m or 26. It's just not at the top of the list yet.

Thanks for info - self assemble trailer - keep me posted! When I learn how to put photos on site i will show you my inherited system - of 4 screw jacks and scaffolding posts to raise boat off trailer, then lower. One hull goes in a dolly that enable you to extend the hulls to assemble...
But your pole idea is great to convert my road trailer to launch capability.
